Claire Danes: Playing Bipolar Is Serious Business : NPR

The second season is about to start for the Showtime series Homeland, a show whose cast and crew are up for numerous honors at the Emmy Awards Sept. 23.

One of them is Claire Danes, who plays a CIA agent who's become obsessed with the idea that an American hero — a Marine returned home after years of captivity in Iraq — has secretly become an operative for al-Qaida. Danes spoke to NPR's Steve Inskeep about preparing for the part, finding the character's body language and being "a big fat ham."

"They talk at a very fast clip. But, you know, it's not a strictly unpleasant phenomenon. A lot of people are reluctant to treat themselves because they're so protective of those manic highs."
